STONE-HANDLING APPARATUS.

C CA N forming part of Letters Patent No. 706,197, dated August 5, 1902.

fierial No. 104,469. (No model) To ctZZ whom, it may concern.-

Be it known that I, CHARLES N. OWEN, a

citizen of the United States, residing at Me-,

chanicsburg, in the county of Cumberland and State of Pennsylvania, haveinvented a certain new and useful Stone-Handling Apparatus, of which thefollowing is a specification, reference being bad therein to theaccompanying drawings.

This invention relates to stone-handling apparatus, the object in viewbeing to provide a complete portable apparatus for handling crushedstone from the time it leaves the crusher until it is delivered to thecarts or wagons which carry the same to the point of final deposit.

In handling broken or crushed stone with a view to delivering the sameinto carts or wagons it has been usual to employ an elevated bin and tomount the same for transportation purposes on a carrying truck orwheels. The bin has necessarily been located at such a height above thewheels as to render the structure top-heavy and-dangerous in moving thesame from place to place. This disadvantage has been increased by thefact that it is necessary to thoroughly brace and support the bin at therequired'elevation to enable it to hold a large quantity of stone,amounting to ten or twelve tens, or even more.

One of the principal objects of this inventoin is to provide what may betermed a portable stone-bin, embodying in connection with a carryingtruck or wheels a bin proper combined with a mechanism for raising andlowering the bin while empty and tilting thebin or adjusting therelative height of the opposite ends of such bin. This also enables thereceiving end of the screen or grader to be brought to the desiredelevation to correspond with the upper discharge end of theelevator,which leads thereto from the crusher.

By means of the construction hereinafter described the bin may belowered to rest directly on the truck-frame, thus providing for safetransportation and removal from place to place and raised to thenecessary elevation while empty and preparatory to discharging thebroken or crushed stone therein by means of the elevator. T

The invention also relates to the particular means for raising andlowering and bracing or supporting the bin when in its elevatedposition.

With the above and other objects in View, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a completestone-handling apparatus, showing a portable stone-bin with screenandother attachments and the stonecrusher and elevator associated with eachother and with the bin in readiness for operation. Fig. 2 is an enlargedside elevation of the portable bin and screen, showing the bin properlowered and resting upon the truck in readiness for transportation. Fig.3 is an end view of the same.

Like reference-numerals designate corresponding parts in all the figuresof the drawings.

' The portable bin comprises an inclined truck-frame 1, consisting ofsuitable parallel longitudinal bars connected at the proper intervals bycross-bars and mounted at opposite ends upon front and rear axles 2 and3, respectively, having carrying-wheels 4. EX- tending upward from thetruck-frame 1, at or near the opposite ends and upon opposite sidesthereof, are corner-standards 5, which are strengthened by inclinedbraces 6. The standards 5 are connected at the top by tierods 7 and atlower pointsby cross-bars 8, the rods 7 forming supports for pulleys 9,around which pass the ropes or cables 10 of the raising and loweringmechanism. 1

- Anyusual or preferred raising and lowering mechanism may be employed;but for the purpose of illustration l have shown at each end of thetruck-frame a shaft or Windlass 11, upon which the ropes or cables 10are wound, as best illustrated in Fig. 3, the ends of said ropes orcables being connected with the adjacent ends of the stone-bin proper,which is indicated at 12 and which is adapted to be moved up and downbetween the standards 5. A short counter-shaft 13, provided with anoperating-crank 14, is geared, by means of, a pinion 15 and spur-gear1b, with the shaft or Windlass 11, the gearing being so regulated as togive the necessary power to enable the bin to be elevated by hand.Pawland-ratchet mechanism 17isemployed in connection with eachcounter-shaft 13 to hold the bin stationary after it has been elevatedto the desired position. It will-of course be understood that theraising and lowering mechanism is duplicated at each end of the bin inorder that the opposite ends of the bin proper may be raised and loweredindependently of each other. In this way one end of the bin may beraised sufliciently to bring itinto the desired relation to thedischarge end of the stone-elevator, while the other end of the bin maybe lowered to give the necessary inclination to the grading-screen,hereinafter described.

As the bin is ordinarily constructed of sufficient size to receive tenor twelve tons of broken or crushed stone, it is important to providemeans for bracing and supporting the bin when in an elevated position,so as to remove the greater portion of the weight from the raising andlowering mechanism and also from the wheels and axles of the truck. Tothis end props or braces 18 and 19 are employed, the braces 18 beinghinged to the truck-frame 1 and adapted to fold downward and rest on theground, as shown in Fig; 1, the braces or props 19 being hingedlyconnected to the end portion of the truck-frame, while the braces 18 arelocated at an intermediate point and preferably about midway between thefront and rear axles. When in use, the braces 18 and 19 are adapted tobe folded upward to the position shown in Fig. 2, where they may be heldby suitable hooks and eyes or other fastening devices 20.

Mounted upon the top of the bin 12 is acylindrical rotary grading-screen21, which has an inclined relation to the top of the bin, as shown inFigs. 1 and 2. This screen is open at both ends and mounted in anysuitable bearings on the top of the bin, so as to rotate freely, and isprovided at one end with a beveled gear 22, driven by a pinion on ashort transverse shaft 23, also provided with a sprocket-wheel adaptedto receive a drive chain 24, which passes around another sprocket-wheelon the shaft 25 at the upper or free end of the stone-elevator, (shownat 26.) The screen 21 is adapted to receive the stone from the elevator,the stone being discharged from the elevator-buckets 27 upon or into achute 28, which leads into the front end of the rotary screen. The binis divided by transverse partitions into a series of compartments withinclined floors and the screen is graded or provided with openings ofdifferent sizes at diflferent points in its length, so as to separate orgrade the stone and discharge the same into the proper compartments ofthe bin. Each compartment is provided at opposite sides of the bin withdischarge-openings 29, in front of which are ar ranged hingeddischarge-chutes 30, provided with suitable raising and lowering tackle,

which enables the chutes to be sustained at any desired angle ofinclination or folded upward out of the way for transportation.

A stone-crusher 31 of any preferred construction may be employed inconnection with the elevator 26, the crusher being driven by a belt 32from any suitable motor and the elevator being driven by a belt or chain33, passing over the shaft of the crusher and the lower shaft 34 of theelevator. 35 designates antifrictional rollers mounted on the bin atproper places to travel against the cornerstandards 5, said rollersserving to properly position and guide the bin as it is raised orlowered and also preventing any binding or cramping of the bin as it ismoved upward or downward.

The portable stone-bin is driven to the point of operation while the binproper is in its lowered position. (Illustrated in Fig. 2.) Under thisarrangement the portable bin may be moved with perfect safety, as it isnot topheavy, as would be the .case were the bin permanently sustainedin an elevated position, as shown in Fig. 1. After reaching the place ofoperation the bin is elevated by the raising mechanism hereinabovedescribed and while the bin is empty. By reason of the independentraising and lowering devices at opposite ends of the bin thereceiving-chute 28 may be accurately adjusted into the proper relationto the discharge end of the elevator 26 after the elevator and crusherhave been associated together and arranged in line with the portable binin the manner illustrated in Fig. 1. The bin 12 may then be given thedesired longitudinal inclination to cause the stone to work its wayalong the length of the grading-screen 21 as the latter revolves. Thestone broken by the crusher 31 is discharged upon the elevator, thelatter carrying the crushed stone upward and delivering it into therotary screen, which in turn grades the stone and discharges it into thebin-compartments. Carts or wagons may then be driven under the properdischarge-chute 30, according to the grade of stone required at thetime, and after. the carts or wagons are loaded the chute 30 may bepartially raised to shut off the discharge of stone. 7 When operationshave been completed, the bin may be entirely emptied of its contents andthen lowered, so

as to rest upon the carrying-truck framel,
